This can lead to a reduction in cramping and urgency associated with diarrhea, providing symptomatic relief for patients suffering from this functional gastrointestinal disorder.

In IBS-D, the goal of treatment is not only to manage the diarrhea but also to address associated symptoms such as abdominal pain and discomfort. Dicyclomine targets these symptoms effectively, leading to an overall improvement in the patient’s quality of life.
